Underwater Digital Cameras (Sony, Canon & Nikon)

Usually underwater digital cameras are used by serious professionals and are not a general piece of photographic equipment you can buy just anywhere. The likes of marine biologists and other scientific personnel use underwater digital cameras to study life beneath the waves. Many waterproof cameras are ok but they cannot be submerged for more than a meter below the surface of the water.

In fact the only way you are really going to get to use an underwater digital camera is if you buy one of these small specialist cameras that are able to be submerged for short periods.

There are very few true underwater digital cameras, as cameras are electronic and cannot withstand water and water pressure. Some of you may have seen or tried the cheap solution to this problem that comes in the form of a plastic casing. These cases have been very popular, especially with people on holiday that want to take a few underwater snaps with their favorite digital camera.

advised to take note of a few facts which should help produce better results.

Remember that as you farther down you go underwater, the more the light diffuses. Owing to the waters diffusing action, all images end up darker than a normal photo out of the water but this can be avoided if a few simple settings on the cameras white balance facility are adjusted. The water also has a strange effect on how the pictures look giving them the appearance of being magnified. To ensure the correct image will be taken you will have to pay a little more attention to the shot you are taking.

On the subject of checks prior to going underwater, it is a good idea to make sure the digital camera case doesn’t leak so submerge it underwater for a short while just to confirm it will be ok when you dive. Especially check the seal to make sure that a grain of sand or even a hair hasn’t broken the seal. Small silica gel packs can be useful if they can fit in the case without causing an obstruction.

Ask your underwater digital camera supplier if you can add extra lenses to complete the kit. If you enjoy looking at things close up then you will need to fit a macro lens.

When you have finished using your underwater digital camera be careful to wash it thoroughly to make sure all the salt water is removed as the salt will crystallize and this can cause leaks. In particular where sand is present then a stream of water to rinse it off is best.

Manufacturers who can supply this type of equipment are Sony, Canon and Nikon, so to find out more log onto their web sites.
